OK, here's my scenario. *I have a typical ranch/rambler with the attached
garage on the front in an L-shape. *Previously a small part of the
garage-to-house entry was boxed in to create a laundry room, and this is
where the water heater also lives.

What I want to do is add an outside water spigot on the front of the garage.
The simplest way is to tap the cold water line in the laundry room, go up
into the garage roof framing, over and then down the front wall. *The
laundry room is heated space, but the garage has been known to freeze in the
winter, so I'll add a cutoff inside the heated space.

Mainly my question is one of material. *The obvious best is rigid copper,
but that's a buttload of work, expensive, and I'm lousy at sweating. *Plus I
have a semi-enclosed bit of framing where I have to make a 90-degree turn
and can't really get in to lay pipe.

CPVC? *Affordable and not hard to use, but the same problem with getting
through that boxed-in bit of framing.

PEX? *I like it, but have never worked with it, and I don't have the right
tools.

PVC? *Indoors?

My gut choice for this is polyethylene tubing, the same stuff we use to pipe
the refrigerator's ice maker. *Very affordable and easy to snake through
enclosed spaces with no joins. *I used the 3/8" stuff a few years ago to add
a filter housing to my kitchen sink, using the push-lock poly fittings.
Very easy and no leaks to date. *But is it anything like code compliant?

Have you considered PEX and Sharkbite fittings?

No tools required other than a sharp blade. Yes, there are PEX cutting
tools, but a sharp blade works just fine, especially for one-time
jobs.

There is also a ~$3.00 tool for removing Shark Bite fittings, but they
can be disconnected without it.

Shark Bite fittings are a bit more expensive than other fittings, but
for what sounds like one-time job, they may be well worth the money.

Shark Bites work for Copper and PEX, so transitioning between the 2
materials requires no tools - other than a pipe cutter for the copper.

My HD has a whole display set-up of the different fittings. If I
needed a large number, I'd go to a plumbing supply store, but for one
or two, HD is fine.

Look here - it really is this easy.
